Definitions

  • the invention relates to a spinning device for melt spinning and cooling endless multifilament chemical threads according to the preamble of claim 1.
  • a melted polymer is extruded into a large number of strand-like filaments.
  • the polymer melt is guided by a pump via lines to one or more spinneret pots.
  • the spinneret pots contain a spinneret plate which has a large number of spinneret bores.
  • the pump, lines and spinneret pots are housed in a heated spinning head. After the filaments extruded through the spinneret bores have been cooled by a cooling device, for example by an air stream, the bundles of filaments are combined to form a thread and the thread is further processed.
  • a cooling device for example by an air stream, the bundles of filaments are combined to form a thread and the thread is further processed.
  • four, six or more spinneret pots are housed closely in a row in a spinning head.
  • the air stream cooling the filaments is passed through a cooling tube together with the filaments and parallel to the filaments at high flow speed.
  • a device for performing such a method is described, for example, in WO 99/067450 (Bag 2623).
  • a suction fan is provided at the end of the cooling pipe in order to maintain the required flow rate.
  • the cooling air is fed to the cooling pipe through a sieve cylinder at the upper end of the cooling pipe.
  • Spinning pots accommodated spinneret plates in the spinning head in a very narrow Division are arranged. On the one hand, this is due to the fact that the available space in the spinning head is limited, on the other hand, the spinneret plates and the spinneret pots associated therewith have large diameters, particularly with high numbers of filaments.
  • DE 34 06 347 AI (Bag 1326) discloses a possibility of sealing a cooling tube with a blow box surrounding the blow tube in such a way that the cooling tube and blow box can be shut down for operations.

  • the heat insulating agent prevents the heat from flowing out of the spinning head into the spinning shaft.
  • the sealant connects the spinning head and cooling tube in an airtight manner and is designed to be separable.
  • a sealing unit is understood here to mean all the means that are required to seal a cooling pipe with a
  • cooling tubes are designed with a smaller diameter and can thus be arranged in a narrow division, and that the sealing unit can also be used with non-gas-tight spinning heads.
  • the spinning device according to the invention is preferably designed with the features according to claim 2.
  • the sealing unit lies essentially within an envelope contour determined by the cross section of the spinneret cup.
  • the separating surface arranged on the spinning head side is arranged directly on the spinneret plate.
  • the separating surface on the spinner head is attached to a fastening means for the spinneret pot or arranged on a fastener for the spinneret plate. This saves further installation space and a particularly narrow division of the spinneret pots is achieved.
  • the spinning device according to the invention can be designed according to claim 6. As a result, the introduction of heat from the spinneret into the sealing unit is greatly reduced, so that the sealing unit does not have to have extreme temperature resistance.
  • the separating surface arranged on the cooling tube side is advantageously formed directly on the end face of the cooling tube facing the spinning head.
  • the functions of isolating and sealing are separated from one another.
  • the sealing unit has an insulating body for thermal insulation and a sealing element for sealing.
  • the insulation is hot
  • Temperature level of the seal lowered, so that temperature-sensitive materials can be used for the seal.
  • the temperature level of the seal can be reduced even further.

  • a spinning device according to the invention is shown.
  • the melt 1 is fed to the heated spinning head 3 via the melt line 2.
  • a pressure booster and distributor pump 4 is accommodated in the spinning head and distributes the supplied melt to the spinneret pots 6 via the distributor lines 5.

  • the cooling air 11 enters through the upper area of the cooling tube 12.
  • the upper region of the cooling tube 12 is formed by a gas-permeable sieve cylinder 10.
  • a sealing unit 9 is formed at the front end of the cooling tube 12 and below the spinneret 6. With the help of the sealing unit 9 it is prevented that secondary air flows in between the spinneret 6 and the cooling tube 12 and leads to undesired cooling of the spinneret 6 or of the filaments 8 immediately after the outlet from the spinneret 6.
  • the filaments 8 leave the cooling tube 12 through a lower opening and are combined into a thread 16 by means of a preparation device 15, which is then further processed and wound up.
  • the entire cooling tube 12 can be lowered by means of a lifting device 14.
  • the sealing unit 9 is separated in a joint formed by a separating surface arranged on the spinning head side and a separating surface arranged on the cooling tube side.

  • the spinneret pot 6 has a collar 6.3 which, in the figure, extends over the underside of the Spinning head 3 protrudes.
  • this collar 6.3 is flush with the underside of the spinning head or protrudes into the spinning head 3. This is particularly advantageous from the point of view that the collar leads to undesired heat radiation.
  • Two different sealing units 9 are shown here by way of example on the right and left sides of the center line.
  • the collar 6.3 has a sealing surface 9.3 on the underside, against which the seal 9.4 is pressed.
  • the seal 9.4 is designed as a heat-resistant and poorly heat-conducting sealing ring, for example made of a cord made of ceramic fabric or high-temperature-resistant silicone.
  • Sealing cord 9.4 is firmly connected to the cooling tube 12 here. In the operating position shown, the sealing unit 9 closes the cooling tube 12 in a gas-tight manner

  • the cooling tube 12 is shut down and the sealing unit 9 is separated between the separating surfaces 9.5 and 9.6.
  • the seal 9.4 remains on the cooling tube 12.
  • a sealing unit designed as a labyrinth seal is shown, which, although not sealing gas-tight, has a very high flow resistance with respect to the gas-permeable cooling tube wall 10, so that only very low leakage air flows are to be expected here.

  • the exemplary embodiment shown in FIG. 2 is particularly suitable for spinning devices in which the spinneret pots are arranged within the spinning head at a very short distance from one another. Since the outer dimensions of the sealing unit 9 and the cooling tube 12 do not protrude beyond an envelope contour defined by the cross section of the spinneret 6, the division of the spinnerets can easily be carried out in the area of the cooling device. The outer diameter of the cooling tubes is adapted to the spinneret bowl.

Abstract

L'invention concerne un dispositif de filage pour filer un fil (16) synthétique multifilament. Sur la face inférieure de la tête (3) de filière sont disposés de manière rapprochée des pots (6) de filières dotés de filières (7.2), à travers les trous (7.1) desquelles des filaments (8) sont extrudés. Les filaments (8) traversent des tubes de refroidissement (12) disposés sous les filières (7.2) et en liaison avec un générateur (13) de flux d'air créant un courant dans le sens de passage du fil en machine. Selon l'invention, chaque tube de refroidissement (12) est rendu étanche au pot (6) de filières directement par une unité d'étanchéité (9), qui forme ainsi une surface de séparation (9.5) du pot (6) de filières disposée du côté de la tête de filière et une surface de séparation (9.6) disposée du côté du tube de refroidissement (12), permettant ainsi une conception très compacte de la tête (6) de filière et du tube de refroidissement (12). Cette unité d'étanchéité (9) est amovible, afin de pouvoir sortir le tube de refroidissement (12) pour des travaux de service et d'entretien.
